Smart Building Integration and Device Hub

4. The mobile device of claim 1, wherein the memory comprising the instructions, that when executed by the processing circuitry, cause the processing circuitry to send the indication over a voice over Internet Protocol (VoIP) channel to the recipient device.

5. The mobile device of claim 1, wherein the memory comprising the instructions, that when executed by the processing circuitry, cause the processing circuitry to send the indication as a text message to the recipient device.

6. The mobile device of claim 1, wherein the memory comprising the instructions, that when executed by the processing circuitry, cause the processing circuitry to send the indication over a plain old telephone service (POTS) channel to the recipient device.

7. The mobile device of claim 1, wherein the memory comprising the instructions, that when executed by the processing circuitry, cause the processing circuitry to receive the URI via a wireless interface, wherein the wireless interface comprises one of a Bluetooth interface, a Near-Field Communication (NFC) interface, a WiFi interface, and a low energy short-range interface.

8. The mobile device of claim 1, wherein the virtual intercom interface is configured to launch in a mobile application associated with the smart building system based on the URI.
